If she found blood on her knuckles she is טמאה
- She checked herself with one hand and the blood went onto the other hand.
- She might have checked herself with either hand.
- Both hands are always likely to touch אותו מקום.
- Nidah is דאורייתא so we are חושש for unusual scenarios.
- Machlokes A&C.
אין שונין בטהרות means
- We do not learn the same Halacha twice in Taharos.
- One does not set up a בית מדרש to learn only Mishnayos in Taharos.
- We do not say our own חידושים on טהרות.
- We do not simulate an incident and assume the same will happen again concerning טהרות.
- Machlokes B&D.
Leah checked her garment and lent it to Rachel who found a כתם there.
- Rachel can claim Leah did not check well so she is exempt from the laundry fees.
- Leah is טהורה and Rachel is טמאה.
- איבעיא דלא איפשטא
- Rachel is a שואל so she is חייב באונסין.
- Both A&B are true.
2 women dealt with a bird with blood the size of a Sela and each found a כתם of a Sela.
- They are both טמאות.
- They are both טהורות.
- The one who found it first is טהורה and the one who found it afterwards is טמאה.
- They decide amongst themselves which one is טמאה.
- It is better not to ask the Rabbi such a question.
There were lots of חזירים in the city דדוקרת
- True, since this was a city of רוב עכו"ם
- False, but כתמים found there were טהורים since there were lots of butchers there.
- False, but there were other animals there that eat שקצים ורמשים and splash blood.
- False, because it was in ארץ ישראל where on may not raise חזירים.
- Machlokes B&C.
According to the first לשון do we pasken עד ועד בכלל?
- According to the מסקנא this is a מחלוקת between Rav Huna and Rav Chisda all over Shas.
- כתמים are דרבנן so לקולא we say עד ועד בכלל
- Rav Huna says we always go לחומרא on this.
- Rav Chisda says we are always מחמיר with the exception of כגריס של כתמים.
- Both C&D are true.
